GUIDEMYOKE BRACKET..

SPECIFICATION forming part of Lettersrlatent No. 696,483, dated April 1, 1902.

Application led November 7,1901. Serial No. 81.4.75. (No model.)

T a/ZZ when@ zit may concern,.-

Be it known that I, JOHN PLAYER, of Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Guide Yoke Brackets, of

which improvement the following is a specification.

'Ihe object of my invention is to provide simple, strong, and inexpensive means for lo supporting the piston-rod guide-bars of a locomotive-engine from the boiler thereof independently of the frame.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure lis a diagrammatic side view of the forward portion of a locomotive-engine with myimprovement applied; Fig. 2, a vertical transverse section on the line a a of Fig. l; Fig. 3, a side zo View, in elevation and on an enlarged scale, of a bracket detached; Fig. 4, a rear view of the same; Fig. 5, a plan or top View, and Fig. G a horizontal sect-ion on the line Z) b of Fig. 4.

My invention is herein illustrated as applied in connection with a locomotive-engine, which is supported on driving-wheels l, only one pair of which is shown, and leading wheels 2, the smoke-box 4 of the boilerl being connected to the frames 8 through the interme- 30 diation of cylinder-saddles l2 in the ordinary manner.

In the practice of my invention the guidebars ll of each of the piston-rods of the locomotive are connected to and supported by an integral guide-yoke bracket of cast metal, (preferably steel,) having a substantially vertical body 10, on the edges ofwhich flanges are formed, so that it shall be of channeled cross-section, an upper horizontal flange l0, a lower horizontal flange 10b, and an upper vertical flange 10c. -The upper and lower fianges are preferably, as shown, stiffened by edge and intermediate flanges or ribs. The bodies of the guide-yoke brackets stand on the inside of the guide-bars--that is, between said bars and the frames and the upper oneV of the guide-bars ll on each'side of the engine is bolted to the upper horizontal flange lOa of one of the brackets through a suitable number of bolt-holes formed therein, and the lower guide-bar is similarly connected to the lower guide-bar 10b. A guide-yoke 9, having downwardly-depending lateral arms, is secured to one of the waist-sheets of the boiler 4. in a transverse planeintersecting the guidebars 1l at any desired point in their length, the connection of the guide-yoke to the boilersheet being preferably made through angleirons 9, bolted or riveted to its opposite sides and riveted to the boiler-sheet, and the lateral arms of the guide-yoke are bolted to the vertical flanges l0c of the brackets.

Under the abovedescribed construction the guide-bars are supported directly by the boiler independently of the frame members, and, as in the type of locomotive shown, may be supported at a point in their length at which a direct connection of the guide-bars .to the frames could not be made by reason of the interposition of a pair of driving-wheels. It will be seen that the brackets may be made of ample strength without being of undue or excessive size or weight and that the guidebars may be readily put in place and taken down, as required, by the ordinary manipulation of their bolt-and-nut connections with the guide-yoke.

I claim as my invention and desire to secure by Letters Patent l. An integral cast metal guide yoke bracket for locomotive guide-bars, having a substantially vertical body, an upper horizontal flange for attachment to an upper guide-bar, a lower horizontal flange for attachment to a lower guide-bar, and an upper vertical flange for attachment to a guide-yoke.

2. An integral cast metal guide yoke bracket for locomotive guide-bars, having a substantially vertical body, of channeled section,ribbed upper and lower horizontal flanges for attachment to an upper and a lower guidebar, respectively, and a ribbed upper vertical flange for attachment to a guide-yoke.

3. In a locomotive-engine, the combination of a guide-yoke secured to the boiler, upper and lower guide-bars, and guideeyoke brackets, each having an upper horizontal flange bolted to one of the upper guide-bars, a lower horizontal flange bolted to one of the lower guide-bars, and an upper vertical flange bolted to one side of the guide-yoke.
